Well.... these are very similar bikes. We don't see the Milano brand around here, but the component spec is about in the ballpark for that price range. However, IMO, it is not That much nicer than the Diamondback you can get from Nashbar.
This type of bike is becoming more and more popular, since folks were taking the gnarly mountain bikes they'd bought and found they never took offroad....And putting street tires on them.
Best is to ride each one, see how it fits you, and see if the dealer will be willing to deal with you a little. (don't expect much on a bike in this range, the profit margin is pretty thin.)
